obtained it iVeqiieiitly from trawlers working on the so-called 

 " witch "-ground of the Moray Firth, and has written an 

 interesting account of its habits, food, and distiibiition. 

 Mr. Thomas Scott, Naturalist to the Fishery I'oard for 

 Scotland, has also met with various examples olF the Firth of 

 Forth. The species therefore is probably an inhabitant of 

 the deeper water all along the eastern coast of Scotland. 

 Dr. Giinther*, again, records it from the west coast of 

 Scotland, but he overlooks the original description of it as a 

 British tisji by Dr. Da}'. .Mr. Sim seems to think that it is 

 fossoriul, but no certainty exists, though allied forms have this 

 habit. 



Collett states that L. I am pet nv for mis is known to occur on 

 the coast of Greenland, Iceland, Spitzbergen, and the shores 

 of North-western Europe as far south as the Cattegat. But 

 i^vf examples of the species have been hitherto obtained from 

 Greeidand and Iceland. Otf S[iitzbergeu, however, it has 

 been repeatedly observed, individuals having been taken on 

 each of the Swedish expeditions to the Polar Sea, and its 

 range extends as far north as 80°. Along the coast of 

 Norway, from Finmark to the Christian ia Fjord, it would 

 a])pear to be rather a common fish, and he mentions having 

 taken a dozen at a single haul of a net iu the Porsanger 

 Fjord, West Fiimiark. 



Two other species of the geims, viz. L. medius and L. macu- 

 latitSj occur in northern waters, the former from Greenland 

 and Spitzbergen, the latter from the same region as well as 

 the shores of Norway and the eastern coast of North America. 

 In L. macidatus the anterior part of the dorsal is somewhat 

 ditferentiated, being furnished with short sharp spines and 

 only a trace of tin-membrane. 



5. On Rhombus (Zeugopterus) norvegicus, Giinther. 



A fine example of this comparatively rare form came from 

 the same region as the preceding si)ecimen, viz. south-east of 

 the Carr lightship, on the 6th April, 1894. 



The species was first described and figured as British by 

 Mr. Couch t under the name of Ilhombus cordina^ Cuv., or 

 Ekstrbm's topknot, from a specimen obtained in the Bristol 

 Channel in 18(53. Dr. Giiutlier, who pointed out the distinc- 

 tion of the British form procured otf Shetland, and also that 

 of Fries and Ekstrbm, from the Fleuronectes cordinu of (3uvier, 

 gave it the name of Rhombus norvegicus %. No additional
